236389-21-2 - Introduction
9,9 '-spirobi[fluoren]-2-ylboronic acid is an organic compound with the chemical formula C26H17BO2. It is a white to light yellow crystal powder that can be dissolved in some organic solvents, such as methanol, dichloromethane, ethanol, etc.
9,9 '-spirobi[fluoren]-2-ylboronic acid has a wide range of applications in the field of organic synthesis. As an organic boron reagent of aromatic compounds, it can participate in Coulomb coupling reaction, borate coupling reaction and so on. It can be used to synthesize organic functional materials such as fluorophores, fluorescent dyes and heterocyclic compounds.
There are two main methods for preparing 9,9 '-spirobi[fluoren]-2-ylboronic acid. One is obtained by reacting the Spiro compound with boric acid, and the specific step is to suspend the Spiro compound in a methanol solution of oxidized boric acid under an inert atmosphere, trimethoxyborane (Me3OB(OH)) is then added and the reaction stirred for a period of time, and finally the product is filtered. Another method is synthesized by reacting an organic compound phenylacetylene with trimethoxyborane, and the specific operation is that phenylacetylene is added to a methanol solution of trimethoxyborane, and the target product is generated by heating the reaction.
As for safety information, 9,9 '-spirobi[fluoren]-2-ylboronic acid is relatively stable under general conditions, but it is still necessary to pay attention to its fire and explosion-proof properties. During operation, protective glasses, protective gloves and protective clothing should be worn to ensure good ventilation conditions. At the same time, avoid contact with strong oxidants and strong acids. During storage, it should be sealed and kept in a cool and dry place, away from fire and flammable substances. In the event of an accident, flush immediately with plenty of water and seek medical assistance. During use and handling, the relevant safety operation regulations shall be strictly observed. These safety tips are for reference only, please consult the relevant safety manual and literature before specific use.
